Nikon D4 vs D800 in light of the recent dxomarksresults

I've been waiting for Nikon D4 for 3 years and saving up the rather hefty sum to be able to buy it directly when released. However, Nikon really messed up my plans by also releasing D800 with so much similar specs.

Personally I relish being able to capture pictures whenever, wherever. I own a D300 today and I feel that it's lacking low-light capabilities (in terms of focus and iso-performance).

In light of the recent dxomarks results I find it hard for me to motivate a D4 and I'd REALLY appreciate some help here. I've read this forum for years and there's so many amazing photographers here and really intelligent individuals so I figured if I'm going to get an answer anywhere, it's here. Hopefully this will also help someone else walking around with the same predicament.
